Q4008R456

Triacs Overview

The Q4008R456 is a TRIAC from the Teccor brand, part of the Qxx08xx series designed for AC switching and phase control. It features an 8 Amp RMS on-state current capability with a standard voltage rating of 400 V. This device operates in Quadrants I & III, triggered from the AC line, making it suitable for motor speed controls, temperature modulation, and lighting applications. The component utilizes a robust package design to withstand voltage transients up to 1000 V generated by switching events.

Triacs Feature Summary

• Sensitive gate control ensures reliable operation in digital control circuitry quadrants
• Standard type devices operate in Quadrants I & III triggered from AC line
• Robust junctions withstand voltage transients up to 1000 V from switching reactions
• L-Package offers UL recognition for 2500Vrms isolation

Triacs Applications

• Motor speed and temperature modulation controls
• Lighting controls
• Static switching relays

Triacs Procurement Notes

Verify the specific suffix R456 against official Littelfuse documentation to confirm exact pinout and packaging variations. Ensure compliance with RoHS standards and check peak reflow temperature limits during assembly. Confirm agency approval numbers match project requirements before finalizing procurement.

Triacs Selection Notes

Select this TRIAC for applications requiring standard quadrant triggering from the AC line. Verify that the 400 V rating meets the system's peak reverse voltage needs. Consider the 8 A RMS current capacity relative to load requirements. Ensure the L-Package isolation rating suits the safety insulation requirements of the target equipment.

Triacs Part Context

This component belongs to the Teccor brand Thyristors family, specifically the 8 Amp Sensitive, Standard & Alternistor Triacs series. The Qxx08xx series provides bi-directional solid-state switching solutions. These devices are engineered for reliability in AC power control environments, offering glass-passivated junctions for parameter stability.

Triacs Replacement Considerations

Check for direct substitutes within the Qxx08xx series or compatible TRIAC families with matching 8 A current and 400 V voltage ratings. Verify equivalent trigger characteristics and package dimensions to ensure mechanical compatibility without redesigning the PCB layout.
